nginx and php-fpm returning 404 on static content

Question

I am trying to have nginx on container 1 connect to the php-fpm running wordpress on container 2 on port 9000. It seems to work for dynamically generated content, such a post, but static content such as CSS, JS or images return a 404. What might be causing this?

Please note that the first "server" block is intended to catch all non-HTTP requests and redirect them to HTTPS, while the second is intended to be "catch all" for those sent "mysite.com".

Thank you,
